4.3. Step-by-Step Assembly
- Measure the Window Opening: Carefully measure the exact dimensions of your window opening where the screen will be installed.
- Cut Profiles and Mesh: Based on your measurements, cut the aluminum profiles, strips, brush seal, and fiberglass mesh to the required size. Ensure precise cuts for a snug fit.
- Assemble the Frame: Connect the cut aluminum profiles using the corner connectors. Use a rubber mallet to gently tap the profiles into place, ensuring a secure and square frame.
- Install the Mesh: Lay the fiberglass mesh over the assembled frame. Secure it tightly using the provided spline and roller tool (if included) or by carefully pressing it into the profile groove. Trim any excess mesh.
- Attach Sealing Brush and Handles: Install the sealing brush around the perimeter of the frame. Attach the small handles to the side tabs for easy handling.
- Prepare Mounting Brackets: Bend the four stainless steel mounting brackets to match the thickness of your window frame (5 to 35 mm).
- Hang the Mosquito Screen: Carefully hang the assembled mosquito screen onto your window frame using the prepared mounting brackets. The drill-free design ensures your window frame remains intact.

6. Maintenance
To ensure the longevity and effectiveness of your mosquito screen, regular maintenance is recommended:
- Cleaning the Mesh: Gently wipe the fiberglass mesh with a damp cloth to remove dust and debris. For stubborn dirt, a mild soap solution can be used. Rinse thoroughly with water and allow to air dry.
- Cleaning the Frame: Clean the aluminum frame with a damp cloth. Avoid abrasive cleaners that could damage the finish.
- Inspection: Periodically inspect the mesh for any tears or damage. Check the frame and corner connectors for stability.
- Storage: If removing the screen for the off-season, clean it thoroughly and store it in a dry, protected area to prevent damage.

7. Troubleshooting
If you encounter any issues during assembly or use, consider the following:
- Difficulty in Assembly / Frame Deformation: Ensure all measurements are precise before cutting. When assembling the frame, apply even pressure and use a rubber mallet gently to avoid bending the profiles. If the mesh is too tight, it can deform the frame; ensure it is taut but not excessively stretched.
- Screen Does Not Fit: Double-check your window opening measurements against the cut profiles. Small adjustments may be possible, but significant discrepancies might require re-cutting profiles or mesh.
- Insects Still Entering: Verify that the sealing brush is properly installed around the entire perimeter of the screen and that there are no gaps between the screen and the window frame. Check the mesh for any unnoticed tears.
